Description
Technical field
The utility model relates to carload detection technique field, is specifically related to a kind of truckload detection system.
Background technology
The detection of charge of trucks goods has been unusual proven technique, the goods weight of charge of trucks generally detects at " weight house ", weigh for the first time, detect the general assembly (TW) of lorry and goods earlier, lorry unloading back is after pound once, draw the lorry gross weight, the data difference that both sides are detected is the goods gross weight.Though this method is accurate, but testing process need be carried out in specific place, if need the vehicle of detection more, then be prone to and block up, lose time, and when the large-tonnage lorry need detect load-carrying, generally be difficult to find large-tonnage " weight house ", as handling goods repeatedly, need repeatedly weigh, then increase expense, lose time.
At present, along with the progress of science and technology, the detection of truckload also is with rapid changepl. never-ending changes and improvements, and Chinese patent ZL200810197488.6 discloses a kind of car load deadweight pick-up unit, comprises automotive suspension flexible member, displacement transducer and signal processor; Displacement transducer is arranged on by the suspension flexible member, and displacement transducer is connected with signal processor.Though this pick-up unit can accurately detect complete vehicle weight, but the installation of the displacement transducer in this device need be punched at the load-bearing axle of automobile, and the goods that lorry carries is generally heavier, if punch at the load-bearing axle, destroy the integrality of load-bearing axle, be prone to potential safety hazard; And the vehicle difference, steel plate elasticity coefficient difference, the displacement gap is bigger, and displacement transducer needs production plurality of specifications, model, manufacturing cost is higher, difficulty is big, causes the cost of whole detection device higher.
The utility model content
The purpose of this utility model is: a kind of truckload detection system is provided, needs at the automobile load-bearing axle sensor installation that punches to solve traditional pick-up unit, be prone to potential safety hazard, problem that cost is high.
The technical solution of the utility model:
A kind of truckload detection system, comprise the load-bearing axle, be installed in load-bearing axle upper end container, be installed in elastic shock attenuation support mechanism between load-bearing axle and the container, be arranged symmetrically in the induction installation of load-bearing axle both sides, wherein: described induction installation comprises component spring and sensor, sensor is installed on the load-bearing axle by anchor ear, spring is installed between described container and the sensor, and described sensor links to each other with signal processor.
Described sensor is pressure transducer, the deformation quantity that its energy accurate Calculation component spring produces, thus calculate accurate elastic force value.
Be embedded with pad between described sensor and the anchor ear, be used for adjust the setting height(from bottom) of each vehicle and prevent that sensor and anchor ear are rigid and contact, can also regulate sensor height.
The beneficial effects of the utility model:
Compared with prior art, the truckload detection system that the utility model provides is installed and fixation of sensor by adopting anchor ear, does not destroy the load-bearing axle of automobile, has alleviated the work load of load-bearing axle, has avoided the appearance of potential safety hazard; And adopt component spring and pressure transducer to replace displacement transducer, not only effect is identical, also has the advantage that price is low, cost is low simultaneously.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that data of the present utility model are handled block diagram;
Among the figure: 1-load-bearing axle, 2-container, 3-elastic shock attenuation support mechanism, 4-component spring, 5-sensor, 6-anchor ear, 7-pad, 8-signal processor.
Embodiment
Below in conjunction with accompanying drawing and example the technical solution of the utility model is described further, but that desired protection domain is not limited to is described.
As shown in Figure 1, the truckload detection system that the utility model provides, comprise load-bearing axle 1, be installed in load-bearing axle 1 upper end container 2, be installed in elastic shock attenuation support mechanism 3 between load-bearing axle 1 and the container 2, be arranged symmetrically in the induction installation of load-bearing axle 1 both sides, wherein: described induction installation comprises component spring 4 and sensor 5, sensor 5 is installed on the load-bearing axle 1 by anchor ear 6, component spring 4 is installed between described container 2 and the sensor 5, and described sensor 5 links to each other with signal processor 8.Adopt anchor ear 6 to install and fixation of sensor 5, rather than install in load-bearing axle 1 punching, the appearance of the potential safety hazard of having avoided the damage of load-bearing axle 1 and having caused, and adopt component spring 4 to replace the displacement situation that displacement transducer detects container 2 simultaneously, not only effect is obvious but also with low cost.
Described sensor 5 is pressure transducer, its can accurate Calculation the deformation quantity that produces of component spring, thereby calculate accurate elastic force value, precision height not only, and cheap effectively reduces processing cost of the present utility model.
Be embedded with pad 7 between described pressure transducer 5 and the anchor ear 6, it can adjust the setting height(from bottom) of various vehicles, for pressure transducer 5 provides protection, prevents that it from damaging sensor with rigid contact of load-bearing axle 1, effectively promoted serviceable life of the present utility model.
